Then there shouldn't be a problem due to the version since they've obviously updated even past what was the newer version back then. The issue back then was that one source had a clearly older version, which seemed to work worse.
Unfortunately I'm not sure what's wrong in your case. Just to make it clear, does Kies not work at all or are you just unable to connect the phone to it? If it's the latter, have you set the phone to connect to Kies? Do you have other problems when connecting the phone to the computer via USB?
